The U.S. Census Bureau considers mothers the "designated parent," even when both parents are present in the home. When mothers care for their children, it's "parenting," but when fathers care for their children, the government deems it a "child care arrangement." I have even heard a few men say that they are heading home to "babysit" for their children. I have never heard a woman refer to taking care of her own children as "babysitting." A friend of mine ran a team-building exercise during a company retreat where people were asked to fill in their hobbies. Half of the men in the group listed "their children" as hobbies. A hobby? For most mothers, kids are not a hobby. Showering is a hobby.
